Any good suggestions on removing that gray structural adhesive from
otherwise bare aluminum? I thought maybe someone had come up with a
good recipe for getting it off w/o damaging fragile parts.
Thanks in advance,

| Subject: | Flaperon Rigging Problem |
Hello all--- I preparing N443DM (mod IV) for 1st flight and am having a problem
rigging the flaperons!
1st-- the construction manual call out an angle of 19 to 20 deg down from horizontal
on the flaperon bell crank. I also have spec sheets that says the angle
should be 11 1/2 deg. I don't know which is correct.
2nd-- is the flap handle suppose to be full forward until it contacts the cross
tube during the setup procedure.?
Thanks for the help

Hi the Cont. 0-200 would make an excellent powerplant in a Kitfox 5 and up, the
great thing about the 0-200 is no liquid cooling Dual ignition, an engine designed
for aircraft not a auto engine.
While a Champ is a good airplane but the Kitfox is also a great airplane so it
just depends on the type of flying one wants to do. one of the big advantages
of the Kitfox is maintenance and the ability make modifications much easier than
on a certifed aircraft.

| Subject: | Re: What's your prop size/ prop clearance? |
Here is what IVOProp told me about 3 blades and 3:1 trannys;
Rotax 503, 532, 582, 583, 618 with 3:1, 3.47:1, 4:1 gear
ratios or other similar engines with high reduction ratios.
Recommendation is the meDium propeller with 5.5 inch diameter
hub. We can no longer recommend the Ultriaght model propeller
because of harmonics associated with these higher ratios
causing blades to move in the 4 inch diameter hub in the
direction of rotation indicated by the motion detector
tape that cannot be stopped with the torque value.
We no longer give refund or credit for undamaged
parts with Ultralight model on these combinations.
So my next question is based on the fact that I do not have my head wrapped around
prop dynamics. What would be better, a 3 blade ultralight prop or a 2 blade
medium? Based on what I have heard I could probably run 70-72" on either setup
with difference being 2 thick blades or 3 thin. Anyone have some science
or math they can throw at this question?

No you dont need to move the EGT probe when the elbow was chopped. The EGT probe
gets installed at X distance from the face of the piston.
If the plugs are black, and the EGTS are high then I would think of the pitch on
the prop. What is the MAX RPM you can turn on the ground and in the air?

| Subject: | Re: What's your prop size/ prop clearance? |
I did a science project on my brothers kitfox II with 2:62-1 gears. WE had my
72: IVO IFA ultralight prop on it, and for grins and giggles one day I pulled
one of the blades and went 2 blade with it (I was on floats). Dont know what
I was thinking, but I just did it..... With the IFA I was able to dial the prop
in for max TO RPM then bump in more pitch to keep the EGTs under control in
flight... IT SUCKED with the 2 blade. Take off run was about 3000' and it took
me the other 3000' of lake to get high enough to turn down wind so I could
land. I got back on the water, changed my pants and put the other blade back
on and by golly we had an airplane again not a "fly in ground effect" worthless
airboat.
Just my .02 on a personal experience.
FWIW, I am planning on trying out an IVO medium Ground Adjust to see if I get more
thrust than the ultralight blades.

Dan,
from my 1994 classic 4 assembly manual, "Rigging the Flaperons":
step (16): Adjust the flap push-pull tube so the angle between the belly of the
aircraft and the #15049 bellcrank is 11.4 degrees...(A "Smartlevel" is invaluable
for this.)
> 2nd-- is the flap handle suppose to be full forward until it contacts the cross

Yes, that's how I rigged mine.
I also second the vote for the smart level. I rigged mine the old fashion way
with a bubble level and a protractor the first time. That took me several days.
I rigged it again a couple years ago with a smart level in a couple hours.

Lenny, am I to understand that you removed one blade from a three-
bladed prop? And then ran the engine with 2 blades? WAAAAY out-of-
balance? That's what it sounds like to me. Or is this a prop that
allows you to do this. Admittedly I'm out of my league when it comes
to other than a fixed-pitch prop, but this sounds like a recipe for
engine shake, rattle and roll. : )

| Subject: | Re: What's your prop size/ prop clearance? |
For general reference. It is commonly accepted that the longer the prop and the
slower you can turn it the more efficient it is. The fewer blades are moe
efficient than more, ie. Two blades are more efficient than three blades and one
blade (They used to run those with a counter weight to balance) is more efficient
than two.
I run a 72 inch two blade warp prop on a 503 50 horse power with a 3:1 gear reduction.
I used to have a 68: three blade GSC. My impression is the 2 blade
climbs better but is not as smooth as the 3 blade. If I had a 582 I would run
a three blade prop. That seems to be the prop of choice for Kitfoxes with two
strokes.

| Subject: | Ribs for tail feathers |
Does anyone have the thickness of the various ribs used in the vertical
stab/rudder and horizontal stab/elevator for the classic IV with the
large elevator/rudder and the speedster type fairings? I'm drawing up a
set I think will work but the 5mm that the building guide mentions seems
too heavy esp. for the rudder and elevator.
Any good pictures of the same?
Thanks in advance,
Mark Napier

To answer you both- the max rpm is 5850 static and 6300 climbing and 6600
now in colder air flying flat and level. -- there is lots of carbine b
uilt up in the manifold and jug just 3/8 of an inch from the piston all the
way out and not so much a long taxi back to the hanger but carbon built up
allot on the plugs after 31 hrs on my last set and just as black after onl
y6 hrs and one needle adjustment since my last plug change-- malcolm
